Edge-Based Anisotropic Mesh Adaptation for CFD Applications

Abstract : This paper presents an anisotropic mesh adaptation technique relying on the length distribution tensor approach and an edge based error estimator. It enables to calculate a stretching factor providing a new edge length distribution, its associated tensor and the corresponding metric. The optimal stretching factor field is obtained by solving an optimization problem under the constraint of a fixed number of nodes. It accounts for different component fields in a single metric. With such features, the method proves to be simple and efficient and can be easily applied to a large panel of challenging CFD applications.
